B. B. HOPPE FASTENING OR HOLDING DEVICE Filed Aug. 17. 1929 mlmlh @m H IN\`IENTOR Patented Oct. 11, 1932 UNITED STATES BORIS B. HOPPE, `OF KEW GARDENS, NEW YORK FASTENING 0B HOLDING DEVICE- yApplication led August 17, 1929. Serial No. 386,627. y

This invention relates to a device by means of which straps may be .held in adjusted po-k sitions relative to each other. The device comprises two members, one of which is piv- 5 oted to the other with means to cause onefof the members to clamp or grip a strap in one position and permit the strap to be released in another position.

The invention willbe understood from the description in connection with the accompanying drawing, in which Fig. 1 is a perspective view of the device. Fig. 2 is a perspective view of a portion of a modification. Fig. 3 is a perspective view of another modication. Fig. 4 is a longitudinal section through the device shown in F ig. 3. Fig. 5 is a plan view of a sheet of metal from which one of the members is made, and Fig. 6 is a plan view of the other member.

In the drawing, reference character 1 indicates a bottom or base member of the device which is provided with a slot 2 near one end through which the end of a strap 3 can be introduced, and the end turned fback and sewed or riveted or connected in any other convenient way tothe main portion of the strap 3, thus securing the strap to the member 1. A curved lug 4 is connected to each side of the member 1 and extends upwardly with their upper ends provided with holes v5 to receive pivots of the other member of the device. The end of the member 1 opposite the slot 2 is curved to provide a groove 6 for an end of the other member of the device to snap into, as will be described below.

The other member of the device is pivoted to the member 1 and comprises an upper flat side 7, the front end of which is curved around, as indicated at 8, and provided with 4") lugs or pivots 9 that extend into the holes 5 in the lugs 4 that are spaced suliciently far apart to receive the side 7 between them. The upper side 7 of the member may be provided with a rectangular opening 10, the metal at one end of this opening being bent downwardly as indicated at 11, to provide a transverse stop or cross piece against which a strap may be pressed to grip the strap. rlhe end of the side portion 7 opposite the curved end 8 5 is provided with a tongue or projection 12 which may be used for turning the member about the pivots 9. The pivoted member is bent back, `asindicated at 13, so as to provide two resilient .portions or offset plate members spaced apart suiiciently to provide an opening 14 through which a strap 15 may be passed. The lower side 16 of the pivoted member extends back approximately the same distance as the upper side, leaving a space between the upper side7 60 and the lower side 16 through which the strap 15 passes. The lower side 16 is bent at an angle to provide a shoulder 17 in proximity to the cross piece 11 for gripping the strap 15. The downwardly and the'outwardly extending end of the side- 16 is slightly curved, as shown at 18, to provide a rib that snaps into the groove 6 when the device is in the closed or gripping position. c y

When the .upperk or pivoted 'member is turned in the clockwise direction as shown in Fig. 1, with .a strap 15 between the upper side 7 and the lower side 16, the free end of the lower side 16 slides along the top side of the member 1,. betweenthe lugs 4,'thus 75 pressing the shoulder 17 toward thel cross piece 11 and tightly gripping the strap 15.,

The springiness of the metal of the vpivoted member causes the free end of the side 16 to press against the member 1 andwhen the so rib 18 snaps into the groove 6 the partsare securelykept in closed position.l YWhen the device is in the closedposition, the rib'or end 18 will have passed beyond what might be termed `the dead center in a 4plane from S5 the pivots 9 to groove 6,'so that thespring in the metal will cause the end carrying the projection 12 to be pressed downwardly.` The strap 15 can, however, be easily released, simply by pulling upwardly upon the projection 90 12 or even by pulling upwardly upon the free end of the strap 15, thusturningthe pivoted member about the pivotsy 9` in anticlockwise direction. Y

In the modification shown'in Fig. 2, parts 95 similar to those shown in Fig. 1 are designated by the same refe-rence characters with the subscript 2. In this modiicationthe base member 12 is made of U-shape fromV vfiat, metal. The lugs l42 may be located along 100 the inner edges instead of the outer edges of the member. The free end of the lower side 162 of the pivoted member is bifurcated and lies fiat against the top side of the member 12, as indicated at 182.

In the modification shown in Figs. 3 to 6, the lower or b ase member is Vshown as being made of wire, and the upper or pivoted member is shown as being stamped out from a flat metal sheet. The lower or base member is shown separately in F ig. .,6 and lconsists -zof a piece of wire, the main portion 21 of which is bent into U-sha-pe, with outwardly ben-t portions 22 and upstanding portions to provide pivots 23 for the pivoted member.

The pivoted vmember which may also be generally in U-shape, as 4already described for lthe pivoted member in Fig.l 1, maybe stampedont of a sheet of flat metal 211, as shownin Fig. 45,. .The sheet 24 is .cut` along parallel Alines 26, along lines 27 at right angies to the lines 2.6, along parallel lines 28 closer together than .the lines 26, along lines 29 at right angles to the lines 28, along parallel lines ,3.0., and also transversely alonga line 3l connecting ,the 'lines 30 near the ends thereof. The sheet24 is also out transversely along .the line `32 and longitudinally along the ends of the line 32 a short distance.

fThe metal lying between .the lines 26 to 31 is pushed downwardly and forwardly to the form .shown in Figs. 3 and 4. A fiat upper 33 is'left corresponding to the side 7 in Fig. 1, and a lower side 33 is left kcorresponding to .the side 16 in kthis figure. A

Y rectangiilar .opening in the side 33 corre.-

sponding to the .opening 1 0 is provided. The metal that was out along the line 31 is bent downwardly to provide a cross piece 34 corresponding'to the .cross piece 11. A portion ofthe edges .of the sheet 24 in the form of spaced members 35., connects the upper and lower sides 33 and 33 of the pivoted member and corresponds tothe portions 13 in Fig.

A l, when the pivoted member is formed with the spaced members v35at an angle .to the plate n leinbers 433 andu33. The metal along the line 32 is bent. upwardly to provide a shoulder yor transverse gripping projection 36in proximity to the cross piece 34.

The portion .of thelo-wer side 33 of the pivoted member beyond the projection 36 is downwardly and outwardly, as shown at .37, the groove .3,8 being provided lto snap over the portions 22 of the base member in gripping or holding position. In this modification, the strap 3 is shown as being held in place on the lower base member by means of the snap 3.

The operation of the device, as is shownin Figs, k3 to 6, is :similar to that already described, i

l. A fastening device comprising a member having upstanding portions, and a .mem-

ber having offset plate members with free ends one of which is pivoted at its free end to the ends of said upstanding portions and the other of which bears at its free end against the body portion of said first named member.

2. A fastening device comprising a member having upstanding portions, a member having offset plate members one of which is pivoted to said upstanding portions and the yother ofwhich bears against said first named member, and is provided with a transverse Aextension for pressing a strap against y the pivoted plate member.

`3. A Afastening device comprising a member having upstanding portion-s, `and a member having resiliently connected offset plate membersyone ofrwhich is pivoted 'at its end to `said upstanding portions and the other of which bears at its free end against the body portion of said irstnamed member and ez;- tends longitudinally thereof sufficiently to cause said second-named member to be retained in its fastening position. n
